dizzying swallows

Windy conditions at Prospect Lake this afternoon no doubt delighted the swallows . Four species flew over the waters, a dizzying prospect for me watching them and trying to determine what's out there. At least all of them were BARN, with a few TREE and certainly two NORTHERN ROUGH WINGED and a sole BANK.

Try following them in their fast , twisty flight..its.. well hypnotic in a way.
